1.2 Machine Description and Intended Use

This machine is a submersible cutter pump. The Wacker Neuson

Submersible Cutter Pump consists of an electric motor, an impeller with a

carbide tip and cutter plate, a stand, and a metal casing with ports for

water or sewage suction and discharge. During operation, the impeller

cuts solid material until it is small enough to pass through the discharge

port. Power is supplied to the pump through a corded plug or a hard-wired

connection, depending on the installation. The operator connects pipes to

the pump and routes them so that water or sewage is pumped from the

work area and discharged into an appropriate location.

This machine is intended to be used for residential, commercial, and

industrial pumping of waste water with variable solids inclusion. This

machine is designed and intended to operate efficiently up to the flow,

head, and suction lift limits stated within the product specifications.

This machine has been designed and built strictly for the intended use

described above. Using the machine for any other purpose could

permanently damage the machine or seriously injure the operator or other

persons in the area. Machine damage caused by misuse is not covered

under warranty.

The following are some examples of misuse:

• Pumping flammable, explosive, or corrosive fluids

• Pumping hot or volatile fluids that result in pump cavitation

• Operating the pump outside of product specifications due to incorrect

diameter pipes, incorrect length pipes, other inlet or outlet

restrictions, or excessive suction lift or head

• Using the machine as a ladder, support, or work surface

• Using the machine to carry or transport passengers or equipment

• Operating the machine outside of factory specifications

• Operating the machine in a manner inconsistent with all warnings

found on the machine and in the Operator’s Manual.

This machine has been designed and built in accordance with the latest

global safety standards. It has been carefully engineered to eliminate

hazards as far as practicable and to increase operator safety through

protective guards and labeling. However, some risks may remain even

after protective measures have been taken. They are called residual

risks. On this machine, they may include exposure to:

• Electric shock from improper electrical connections or high voltage

2.4 Installing the Pump

Overview

This pump requires careful installation to operate at peak efficiency.

Observe the following recommendations when installing the pump.

Placing the pump

A sample installation diagram is provided below. Contact your Wacker

Neuson dealer for help in installing the pump for your particular

application.

• Install the pump on a flat, smooth surface, such as a concrete

pad.

• Do not place the pump in areas that may be susceptible to

turbulence or may allow the pump to take in air—for example,

near the inlet of a water tank. Install a baffle if it is impossible to

keep the pump away from these areas.

• Install piping so that air pockets cannot form anywhere in the

system.

NOTICE: If the pump is being controlled automatically, discharged water

could flow backwards. This backflow may trigger the water surface control

immediately, forcing the pump to continuously cycle ON and OFF. Perma-

nent damage to the pump may result.

• Install a check valve if the pump tank is deep, or if the vertical

head or the lateral distance is long.

• If the pump is being installed in a permanent location where it is

not readily accessible after installation, request a duplicate

nameplate from Wacker Neuson. The duplicate nameplate

should be installed at the wellhead or on the control box for ready

visibility.

Suspending the pump

The pump may be suspended by a chain. Use a shackle (a) to fasten

the chain to the pump eye bolt (b) as shown in the illustration.

Safety

considerations

• Do not lift or suspend the pump by the cable.

• The chain and lifting apparatus must be capable of supporting the

pump. See Technical Data for weight and dimensional

information.

• Make sure that the chain does not become twisted during

installation. A twisted chain may break, causing the pump to fall.

• Do not operate the pump if the cable is hanging loose. An

unrestrained cable can be sucked into the impeller.

CAUTION

Personal injury or equipment damage hazards. An improperly suspended pump

may fall unexpectedly, causing injury or equipment damage.

f Observe the following safety considerations when suspending the pump.

2.5 Electrical Wiring

General information

• Electrical wiring should be performed by a qualified electrician in

accord with all applicable regulations. Failure to observe this

precaution not only risks breaking the law, but is extremely

hazardous.

• Make sure the pump is equipped with the specified overload

protectors, fuses, and/or breakers. These items are designed to

guard against electrical shock from a current leak or pump

malfunction.

• Operate within the capacity of the power supply and wiring.

Grounding the pump

• Do not use the pump without first grounding it properly.

• Do not attach the grounding wire to a gas pipe, water pipe,

lightning rod, or telephone grounding wire.

Connecting the power supply

• Before connecting leads to the terminal strip, make certain the

power supply is disconnected (i.e. through circuit breakers) to

avoid electrical shock, shorting, or unexpected starting of the

pump.

• Do not use the pump with the cable assembly connected loosely.

• Draw power from a dedicated power outlet rated at 15 A or

above. Sharing the outlet with other equipment may cause

overheating at the branch outlet and could result in fire.

• Use a dedicated power supply with a ground leakage circuit

breaker.

• Tighten the ends of the cable assembly securely against the

terminal board.

WARNING

An improperly wired pump can result in current leakage, personal injury, electrical

shock, fire, or permanent equipment damage.

2.6 Cable Assembly

Extending the cable

If it is necessary to extend the cable assembly, use a core size equal

to or larger than the original. This is necessary to avoid a performance

drop and cable overheating which may result in current leakage,

electrical shock, or fire.

Avoiding cable damage

• Do not suspend the pump by the cable.

• Make sure the cable does not become excessively bent or

twisted.

• Do not allow the cable to rub against a structure in a way that

might damage it.

• Repair or replace a cut or damaged cable immediately.

Submerging the cable

• Do not submerge a cable with cut insulation or other damage.

• If it is necessary to submerge the connection wires of the cable

assembly in water, first seal the wires completely in a molded

protective sleeve.

• Do not allow the cable assembly wires or power supply plug to

become wet.

WARNING

Current leakage, electrical shock, or fire hazards.

f Observe the safety considerations below when handling the cable assembly.
